我正在做一个大项目。我在制作评论回复系统时陷入困境。它适用于 Ajax，但是当我发布第二条或其他评论回复时，文本区域显示为空。为什么只有第一个回复提交成功？这是我的代码：
$(document).ready(function(){
$(".post_reply").click(function(rp) {
rp.preventDefault();
var box_id = $(".bid").val();
var ownerc = $(".owner").val();
var replyc = $(".reply").val();
var commentc_id = $(".comment_id").val();
var dataString = 'bid='+ box_id + '&owner=' + ownerc + '&comment_id=' + commentc_id + '&reply=' + replyc;
alert(replyc);
if(ownerc=='' || box_id=='')
{
alert('Please Give Valide Details');
}
else
{
$.ajax({
type: "POST",
url: "sub_comment.php",
data: dataString,
cache: false,
success: function(replys){
$('#replys'+commentc_id).append(replys);
$(".reply").val('');
}
});
}
return false;
});
});
这是评论系统的完整代码..
